Bond (glue or adhesives) is usually just used for technologic and artistic area – when one manufactures something. However, some elements in bond can work as an addictive drug. The main addictive ones are toluene, methyl acetate, and methanol. 1. Toluene Toluene (C6H5CH3) is a clear liquid which smells like paint thinners. Toluene is an aromatic hydrocarbon; toluene has a certain scent and can be used as an inhalant drug. As a matter of course, being a drug, toluene causes dramatic neurological harm. It can directly damage the person’s brain. Toluene occurs naturally at low levels in crude oil and is usually produced in the processes of making gasoline via a catalytic reformer, in an ethylene cracker or making coke from coal. Final separation (either via distillation or solvent extraction) takes place in a BTX plant. It usually excites people when inhaled. When inhaled little amount, toluene gas can cause people tiredness, confusion, drunken-like behaviors, memory loss, nausea, and con temporary loss in some senses (vision, hearing, and tasting). However, the symptoms stop when exposure is stopped. When inhaled a lot, toluene may result in light-headedness, serious nausea, drowsiness, unconsciousness, and if serious, death. It can also affect kidney. Bibliography: Dec. 11th 2009, Wikipedia – toluene, http://en.wikipedia.org/wiki/Toluene. 2. Methyl Acetate Methyl acetate is a flammable liquid with weird smell like some kinds of adhesives or paints. Like toluene, methyl acetate is used in adhesives, paints, and thinners. Its main usage is a low toxicity solvent in glues, paints, and nail polish removers. Methyl acetate is produced industrially via the carbonylation of methanol as a byproduct of the production of acetic acid. Although not of commercial significance, methyl acetate arises by esterfication in the presence of strong acids such as sulfuric acid. It is kind of central nervous system (CNS) depressants. It inhibits people’s thinking and acting – people tend to become less nervous as if they are drunk. Also, people react more slowly than they usually do.

Methyl Alcohol (Methanol) Methanol, which is also called wood alcohol, is a colorless volatile chemical. Pure methanol is very toxic. 10mL can lead to blindness. 100mL can even lead to death. It smells like usual drinking alcohol (ethanol).
Methanol is produced naturally in the anaerobic metabolism of many varieties of bacteria, and is ubiquitous in the environment. As a result, there is a small fraction of methanol vapor in the atmosphere. Over the course of several days, atmospheric methanol is oxidized with the help of sunlight to carbon dioxide and water.
Because of its toxic properties, methanol is frequently used as a denaturant additive for ethanol manufactured for industrial uses — this addition of methanol exempts industrial ethanol from liquor excise taxation. Methanol is often called wood alcohol because it was once produced chiefly as a byproduct of the destructive distillation of wood.
Methanol is also a CNS depressant. Its initial symptoms are CNS depression, headache, dizziness, nausea, confusion, unconsciousness, and even death. These are usually less severe than the symptoms due to the ingestion of a same amount of ethanol. After 10 to 30 hours after the initial exposure, second symptoms arise – blurring or complete blindness.

1) List three things you learnt about drugs during this project.
1st drugs may result in serious addiction
2nd drugs can not only affect nerve system but also other organs
3rd drugs can be found easily in our everyday lives (like glue)
2) List three things you would like to learn about in the future concerning drugs.
1st treatments to drug addicted people
2nd costs of drugs
3rd origin of drugs
3) List three things you enjoy about using this learning environment (Wiki).
1st people can easily comment on others' page
2nd people can see when the page was edited
3rd people can share one's idea easily
4) List three things you dislike about using this learning environment (Wiki).
1st it is relatively hard to edit compared to microsoft words
2nd i cannot work on it if the internet is too slow or not working
3rd i might easily forget my ID to sign in
5) Do you prefer traditional written essays or creating a Wiki page for assessment?
written essays
6) How do you feel about contributing to other people’s pages
It is quite interesting, but it is hard when i've got nothing to say about the pages.
7) How do you feel about other people contributing to your page?
No one has contributed at, thus i don't know.
8) How do you feel about self-assessment?
It helps me to look back on my work.
Feels little bit guilty by conscience lol
9) Which topic do you feel personally was more beneficial in semester one – drugs or love?
love. because, whether i know about drug or not, i would anyway not do it.
10) If you could choose your own topics for PSE what would you like to study?
To be honest, no idea.
